K-Flex Duct® Liner Gray Insulation is an environmentally friendly, CFC and HCFC-free, closed-cell, flexible elastomeric thermal and acoustical insulation. K-Flex Duct® Liner Gray is used to retard heat gain and prevent condensation or frost formation on cold equipment or ducts. It also effectively retards heat loss when used on hot equipment or ducts. Liner can be used as both duct and air handling equipment liner. Thickness has been calculated to control condensation on cold surfaces. The closed-cell structure and unique formulation of K-Flex Duct® Liner Gray effectively retards the flow of moisture vapor, and is considered a low transmittance vapor retarder. For most applications, K-Flex Duct® Liner Gray needs no additional protection.
